Isa 56:2

“(Verse 2.) Blessed is the man who does this, and the son of man who understands it: who keeps the Sabbath, so as not to pollute it: who keeps his hands from doing evil. LXX: Blessed is the man who does these things, and the person who retains them, and keeps the Sabbaths, so as not to profane them, and keeps his hands from doing iniquity. He who can say with the apostle Paul, 'When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things' (1 Corinthians 13:11): he attains the present blessedness, forgetting the past and reaching forward to the future until he reaches the unity of faith and the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ; so that the psalm may be fittingly applied to him: Blessed is the man who does not walk in the counsel of the wicked (Psalm 1:1). Therefore, this is the man, and the son of the inner man, of whom it is frequently said in Leviticus: Man, man (Lev. XVII, 8): in him is blessedness, because he accomplishes the first and grasps these things: judgment, namely, and justice, and the salvation of the Lord, which is near, and is to be revealed to all nations: so that he not only does what is commanded, but holds fast with a strict hand; and keeps the Sabbath, lest he defile it: Now what the Sabbath is, which he commanded to be observed, the following verse shows: Observing his hands, lest he do any evil. It profits nothing to sit idly on the Sabbath, or to sleep, and to long for feasts. But if one does good, let them rest from evil, and let them have a constant Sabbath of injustice, that is, leisure, and let them only do those things which pertain to the salvation of the soul, and not engage in any servile work. For whoever commits sin, is a servant of sin (John 8). But we have been called to liberty, by which liberty Christ has given us, so that we may not labor for food that perishes; but by cleaving to the Lord, let us say with the Prophet: It is good for me to cleave to God (Psalm 73:28). Let us be of one spirit with Him, and let us observe the dedicated Sabbaths, so that we may not be of the six days in which the world was made, of which the Apostles were not, and of which the Lord spoke: If you were of this world, the world would certainly love what is its own. But now you are not of this world, because I have chosen you, and therefore the world hates you (John 15:19).”

“No one should be exercised by the words said to the Israelites about keeping the law, which doubtless belongs to the shadows of the world of types; for no one is justified by the law with God.… We should understand this spiritually; and abstaining from the care of the flesh we should offer spiritual sacrifices with the odor of a good spiritual fragrance and minister to God … to keep the sabbath spiritually now means for us keeping away from worldly cares … and with holy vigor making him glad, and offering ourselves in holy sweetness.”

“Blessed is the man that does this, that keeps the following precepts, to observe the Sabbath, etc. מחללו From polluting it. It is certain that the ת in שבת indicates the feminine gender; the masculine pronoun וֹ refers to the masculine noun יום day, which may be supplied before שבת, or to the verbal noun שִׁמּוּר implied in the verb שֹׁמֵר; for every verb implies a verbal noun, if that is not directly expressed; compare the remark of R. Moses Hakkohen on וַתִּצְפְּנוֹ (Jos. 2:7), that the suffix refers to the verbal noun the taking; compare also ברב יעצים עצה תקום ═ ברב יעצים תקום, in the multitude of counsellors it is established (Prov. 15:22), the word עצה being supplied.”

“Blessed is the man. Here he sets out the fruit of this counsel in those who receive it. And first, he sets out its utility, setting out the fruit of fulfilling it: blessed is the man that doth this, fulfilling it by his works, and the son of man that shall lay hold on this, undertaking it strenuously: blessed is the man that fears the Lord (Ps 111[112]:1); and the manner of fulfilling it, as to ceremonial precepts: that keeps the sabbath. For the observance of the sabbath belonged to the moral law as to the requirement that rest be placed in God and sometimes freed for divine affairs by abstaining from other things; but it belonged to the ceremonial law as to the determination of the time. Now, for them, the seventh day was determined because of the work of creation, which had as yet been surpassed by nothing worthier; for us, the first day, or the eighth, is determined because of the mystery of the resurrection, in which created nature was restored to something better: remember that you keep holy the sabbath day (Exod 20:8); take heed to your souls, and carry no burdens on the sabbath day (Jer 17:21). And as to moral precepts, that keeps his hands from doing any evil: I will wash my hands among the innocent (Ps 25[26]:6).”
